M16

The cache included American-made firearms, such as M4 and M16 rifles, as well as other older weapons in Afghan possession that had been left behind from decades of conflict.

Israeli media reported that the Palestinian who carried out Tuesday's shooting attack in Tayasir was able to sneak up to a military post next to the checkpoint before opening fire with an M16 rifle at soldiers stationed there.

He says he was detained with M16 rifles in his face, strip-searched, and interrogated for 12 hours.

Years of violent confrontation between the Israeli army and Palestinian armed groups have been etched into Jenin's narrow pathways – bullet-holes scattered across walls, piles of rubble left by military bulldozers, graffiti in the shape of M16 rifles, along with the name "Hamas".

Israel says it has killed 20 armed fighters in the operation and recovered weapons including M16 rifles and explosive devices.
